Integrate the granny flat into your prefabricated house
An example of a prefabricated house with a granny flat in the house is Variant 25-166 - with two planning proposals.
In our variant 1, the residents of the granny flat in the basement share a common entrance with the residents of the main flat on the ground floor and attic.
In variant 2, on the other hand, the granny flat is separated from the main flat by a separate entrance. The option of planning the terraces on different sides of the house also entails a clear separation of the two units.
A good variant for more privacy
A granny flat directly in your house is not quite your cup of tea?
A granny flat does not mean that it has to be integrated into the house: it can also be planned as a single-storey extension. In our Variant 25-150 house design with granny flat, we simply added the additional flat to the house as a cube – compact, at ground level and barrier-free.
Our builder lives with his spouse in the 138 m² main flat and has rented out the 73 m² granny flat to friends.
„I particularly like the fact that both living units are located right next to each other and that you can visit each other through the shared utility room without having to step outside.“
